Court agreed that Clarence was no longer good law. Those who, knowing that they are suffering HIV or some other serious sexual disease, recklessly transmit it through consensual sexual intercourse, and inflict grievous bodily harm on a person from whom the risk is concealed and who is not consenting to it will be liable under s.20. Moreover, to the extent that Clarence suggested that consensual sexual intercourse of itself was to be regarded as consent to the risk of consequent disease, again, it is no longer authoritative. If however, the victim does in fact consent to the risk, this will provide a defence under s.20. Although the two are inevitably linked, the ultimate question is not knowledge, but consent.
